Counterexamples

The gospels contain accounts of Jesus committing sins. At the very least, it is not clear that he never committed any sins.

In Luke 19:29-35, Jesus tells his disciples to steal a horse, which they do. (Mark 11:1-6 tells the same story, but notes that the owners let the disciples take the horse once they found out that it was for Jesus.)

In Matthew 12:46-50, Mark 3:31-35, and Luke 8:19-21, Jesus is preaching to a crowd, when his mother and brothers come looking for him. He denies them, saying, in effect "my followers are my family now."
